​NAULETTE, a large cavern on the left bank of the Lesse, which joins the Meuse above Dinant, Belgium. Here in 1866 Edouard Dupont discovered an imperfect human lower jaw, now in the Brussels Natural History Museum. It is of a very ape-like type in its extreme projection and that of the teeth sockets (teeth themselves lost), with canines very strong and large molars increasing in size backward. It was found associated with the remains of mammoth, rhinoceros and reindeer. The Naulette man is now assigned to the Mousterian Epoch.
